To all whom it may concern:

Be it known that I, Dr. AMANDUS BAR- TELS, a subject of the King of Prussia, residing at Harburg-on-the-Elbe, strasse 102, Kingdom of Prussia, German Empire, have invented certain new and ful Improvements in Processes for the Manufacture of Casein Especially Adapted for the Production of Artificial Hornlike Masses, of which the following is a specification.

The present invention relates to a process of treating casein, for the production of artificial horn-like material.

The freshly precipitated humid casein from skim-milk imparts to artificial hornlike material porous character. This porous particularly disadvantageous in such terial.

In accordance with my process I take freshly precipitated casein (curd), before drying, and subject the same to a strong or powerful grinding action. This grinding the natural layer-structure of the casein, an obtains the finest division of the small particles of the casein. The fresh or humid casein thus treated orground is now allowed to dry. The dried casein is subsequently moistened, and this mass is then-kneaded under high pressure.

character is As a result, there is obtained a clear, transparent, and completely uniform artificial horn-like material free from pores. This material is of course allowed to dry and harden.

It is also found that by the treatment of the casein as hereinabove set forth, the same is adapted to receive or take up a large amount of filling material or agents. filling material 'is preferably added to the fresh or humid casein prior to its grinding treatment, g treatment serves also togrind or finely ing material, which aids in the grinding of the casein.

Any suitable apparatus may be employed to finely divide or grind the fresh or humi casein, such as rubbing or grinding devices,

rolling mills, or other apparatus to efiect the'finest division an distribution of the plastic or humid casein.
